Nother vote for the Airshed Pro.
I use the Airshed all the time and have since it first came out using a different fabric in a hoodless shirt version. At first I was skeptical about the new hooded version because of the combination of fabrics with different properties but it actually works okay in practice. As Philip notes, the polyester fabric on the forearms (same as on the hood) makes it easy to pull up the sleeves — something that was impossible for me and my thick forearms with the constrictive first version. The downside of the polyester fabric is that it doesn’t have the same partial wind cutting properties of the main nylon fabric used in the body. I would have preferred that the nylon fabric be used for the hood to cut more of the wind but I think since this piece is aimed at runners they prefer the aerodynamic form fitting shape of the polyester.
This is a piece that works for me for three seasons. Come winter I prefer greater wind resistance, when a Houdini Air hits the mark for me. Unfortunately, the Houdini Air has been very difficult to find in Europe these past couple of years so I’ve settled for strange sizes/colors — on sale, at least. The Airshed Pro is easy to find but the price has recently gone up in Europe, too. In any case, the Airshed Pro still carries a much more reasonable price than the Houdini Air (even if it were available which it is not). I have purchased women’s XL sizes on sale to save money (40%+ off). Slightly heavier than a Men’s M size, it works for me and saving money on what are basically expendable wind shirts is always a good thing. FYI, the women’s version has an extra panel around the lower back of the pullover, not found on the Men’s, which is designed to pull the fabric around the hips in a more flattering way. Unfortunately, the fabric used in that panel, which must be a spandex blend, dries slower than the Pertex in the main body.
I can wear the Airshed Pro as a base layer or more commonly love using it as a windshirt over a base layer, usually a merino tencel blend.
I liked the Nano Air Hoody, too, until I tried using Polartec Alpha Direct with various windshirts such as the Airshed Pro instead. The combo breathes better, is lighter, more flexible, and manages moisture better for me than the Nano Air Hoody.
